Common features of automatic dosing devices for different applications

- Mar 14, 2018 -

The automatic dosing device is an automatic complete device that injects chemical liquids into various systems according to the process flow. In order to meet the requirements of different occasions, the selected automatic dosing device is also different. For example, the oil field automatic dosing device is mainly used for injecting various liquids such as flocculants, scale inhibitors, corrosion inhibitors, demulsifiers, and the like into wellheads and other systems on the platform in the oil extraction industry.

There are also boiler automatic dosing devices designed for boilers, which are used to add ammonia and hydrazine to boiler feed water, add ammonia to condensate and add hydrazine, stop and add ammonia and add hydrazine, and add phosphoric acid to steam boilers. Salt is mainly used for power plants and power stations. In addition, the water treatment automatic dosing device can be added to tap water, wastewater, and sewage in the water treatment process, and the related water supply and drainage treatment, environmental protection, and other process processes are often used, so the water works, hotels, restaurants, swimming pools, sewage treatment plant will choose the water treatment automatic dosing device.

No matter which occasion the automatic dosing device is used, it adopts the mechanical and electrical integration structure form, all equipped with stirring system, dosing system and automatic control system, plus frequency conversion control system, can realize local control, remote automatic control, manual and automatic mutual conversion dosing; and also has the advantages of compact structure, small size, low noise, stable operation, simple installation, easy operation and other advantages.

More specifically, the automatic dosing device is designed through different processes to precisely configure the solutions of various types of solid and liquid chemicals, and then accurately dosing with a metering pump to meet various design requirements, such as descaling and deoxygenation, coagulation, acid, alkali and so on.

Automatic dosing device feeding process, either manual operation, but also through the PC, magnetic flap level meter, PH meter, stroke controller, inverter and other electrical appliances, instruments, make the medicated device become mechanical and electrical integration Products and achieve automatic control to improve control accuracy.
